For gas, gasoline or oil engines, blowers, etc.
Our Fig 77 glass body gas engine lubricator is designed to feed oil directly into the cylinders of gas engines. The bent tube, shown within the cup, conveys pressure to the upper part of the body where it equalizes pressure on the oil, allowing gravity to feed the oil.
Regulation of the feed is accomplished by the turning of a knurled adjusting nut. Oil feed is started and stopped by raising or lowering a snap lever. Shanks are fitted with ball check to prevent oil from blowing back.
